The effect is also known as the air gap modulation effect and its value has not been precisely estimated up to now. We have used an experimental setup with a Renishaw interferometer to monitor the translation of the air-vacuum interface during the free fall depending on a type of the dropping chamber, tripod legs and anti-vibration pads. The measurement results show that the effect of the air-vacuum interface translation on the g-values is below 0.1 µGal for the recoil-compensated FG5X gravimeter. In case of the FG5 gravimeters, the effect is typically reaching up to 1 µGal and can be corrected with the expanded uncertainty of 0.1 µGal. Our findings reveal that the combined uncertainty of the FG5/X gravimeters has the potential to be reduced.
